corresponding index of an element

I have two vectors

g_counter = [2 0]

and

list = [3 0]

I would get the indices of all the elements belong to g_counter that have their position setted to zero and the corresponding position of list vector has to be setted to 0.

For instance with the given vectors I would get 2 as index. How can I do?

your question is not clear

Answer 1

[Azzi Abdelmalek]

Maybe you want this

g_counter=[1 0 2 2 0] 
list=[1 2 3 0 0]
idx=intersect(find(g_counter==0),find(list==0))

Maybe you had resolved my problem.One minute I check if everything work

Ok problem solved...thanks so much...

Answer 2

[José-Luis]

 idx = find(g_counter == 0 & list == 0);

or

 idx = find(~g_counter & ~list);

or

 idx = find(g_counter - list == g_counter + list);
